These days, technology has changed people's lives and altered too much; moreover, the bad effect has been humans can do every work really fast; as a result, they destroy the environment; then a group of people believed is too late to avoid these happened instead of another group who think we can improve the background and help it to get better. In my opinion, the second view is true, because we can change our situation, and sometimes is really hard, but we must not build limits for ourselves.
